19 ROM protection
19.4 Writing and erasing
19.4.1
19.4.2
1) Write the code 0xa74a9d23 to SECBIT register.
2) Write data within 16 clocks from the above.
Note) The above procedure is enabled only when using 32-bit data transfer command.
Writing and erasing protection bits are available with a single chip mode, single boot mode and
writer mode.
Writing to the protection bits is done on block-by-block basis.
Erasing of the protection bits is done by two groups of the blocks: block 0 through 3 and block 4
through 5. When the settings for all the blocks are “1”, erasing must be done after setting the
SECBIT <SECBIT> bit to “0”. Setting “1” at that situation erases all the protection bits. To write and
erase the protection bits, command sequence is used.
See chapter 18 for details.
Rewriting of the security bits is available with a single chip mode and single boot mode. The SECBIT
<SECBIT> bit that activates security function is set to “1” at a power-on reset right after power-on.
The bit is rewritten by the following procedure.
